IRA H. GREEN, GANANDAIGUA, NEW YORK IMPROVEMENT IN BAND-CUTTER ANDFEEDER FOR THRASHERS.

Specification forming part of Letters Patent No. 219,463, datedSeptember 9, 1879 application filed June 28, 1879.

To all whom it may concern Be it known that I, IRA H. GREEN, of thevillage of Canandaigua, in the county of Ontario and State of NewYork,have invented a certain new and useful Improvement in Band-Gutterand Feeder for Thrashing-Machines; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebeing had to the accompanying drawings, in which Figure l is alongitudinal vertical section of the machine. Fig. 2 is a plan of one ofthe slats of the endless carrier and itsconnections. Figs. 3 and 4 arecross-sections of the devices for removing the wire bands. Fig. 5 is aplan of the dividers and connecting parts.

My improvement relates to band-cutting attachments forthrashing-machines, in which an endless carrier is used to convey thebun dles to the cylinder and band-cutting wheels are employed to cut thehands during their i of the carrier extends some distance back of themachine, to receive the bundles, while the front end rests nearlyvertically over the throat of the cylinder. The carrier is horizontal,or nearly so, and the inner end is so elevated as to produce a drop tothe grain as it passes to the cylinder, all as shown in the drawings. i

The carrier is preferably composed of side bands or straps, connected bycross-slats, and has a table between its lengths, on which the bundlesare supported as they are fed along.

D is a swinging or oscillating feed-board, arranged beneath the innerend of the carrier and directly back of the cylinder. It stands nearlyvertically, or but slightly inclined back-. ward. In width it occupiesthe whole crossarea between the sides of the machine, and in height itcomes-as near the carrier as possible, allowing free working of theparts. On the top edge is a plate, I), projecting backward, and servingto prevent the uncovering of the space under the carrier during thevibrations of the feed-board, and therebyobviating clogging of the partswith the grain. The bottom of the feed-board is preferably forked, ormade of V form, resting and turning on a rib of the concave, but, ifdesired, may be pivoted,'hinged, or otherwise arranged to turn as thefeed-board is vibrated.

F is ashaft, having a crank, c, with which the top of the feed'board isconnected by a connecting-rod, d,- and as said shaft is re- 'volved thefeed-board receives a reciprocatshaft which rests between the sides ofthe machine, and is made removable, or to the crank-shaft F. The ends ofthese dividers pass through slotsh h of the feed-board, and project somelittle distance beyond, as shown. The ends of the dividers are madepointed.

Ordinarily the dividers are stationary, but,v

if, desired, may be made to vibrate vertically or laterally. Thesedividers 'are used in thrashing bundled grain, but are removed inthrashing loose grain.

J J J are the ordinary bandcutting wheels, located on a shaftatasuitable distance above the carrier.

[L L are springs, attached at their upper ends to the casing of themachine above the cutter-shaft. shaft, and are turned beneath the same,to hold the bundle down on the carrier.

10 7c are the cross-slats of the carrier. To these cross-slats, atsuitable distance apart, are attached the devices for removing the wirebands from the bundles, as follows: 1 is a shaft extending across thecarrier, its jourslat.

They pass over and around the 0% Marc a series of curved teeth forminghooks, which are attached fast to the shaft and stand reversely to theline of motion of the carrier.-

p10 are plates attached to the bottom of the slat and extending outunder the teeth so far as to allow the points of the teeth to strikedown on top of them, or into holes formed in them when thrown down. 1"is a spring connected with the slat, which rests over square sides, 8 s,of the shaft, and acts similarly to the. spring in a jack-knife, byholding the shaft in a fixed position when thrown up or down. if t arearms projecting from the shaft, and u u are stops projecting from theinner sides or bottom of the machine, and so relatively arranged that asthe arms strike the stops the shaft will be alternately turned, throwingthe teeth up and down, as shown in Fig. l. The teeth are turned uprightas they pass on the under side of the machine, and remain so till theyhave passed under the cutters, when they v snap down again.

I do not wish to confine myself to the particular means for operatingthe shaft as above described, as it is obvious that different meansmight be used with the same result, the es sential thing being to raisethe teeth and to cause them to fall again at the proper ,time.

The operation of the machine is as follows The teeth a n being elevatedat the induction end of the machine, the bundle is laid longitudinallyon the carrier, with the band just in the rear of the teeth. As thebundle passes under the cutters the wire band is cut, while at the sametime, or immediately thereafter, the teeth snap down and hook throughthe band, and hold the same between themselves and the plates 2 9 tillthey reach the under side, when the teeth open and allow the band tofall off. By this means the wire bands are effectually remoy'ed from.the grain, and the difficulty heretofore experienced of having the wirepass into the space between the cylinder and concave is avoided. Thedevices for removing bands may be dispensed with when wire is not used.

As the grain passes over the discharge end of the carrier it falls downendwise to the cylinder, and is spread or divided by the dividers ff,which separate the bundle and spread itin a thin sheet, at the same timeholding back on the straw, so that it is not fed too fast to thecylinder and is not drawn too fast through themachine. The feed-boardDforms a diaphragm or wall, holding the grain up to the cylinder, and byits vibratory motion forces the straw into the cylinder and obviates anyback action.

Any desired number of the shafts l and teeth a may be used.

Having thus described my invention, what I claim as newis- 1. In aband-cutter and feeder for thrashingmachines, the combination, with thecylinder B and elevatedcarrier E, of the feed-board D, standing uprightbetween said parts and receiving a "ibratory motion forward and back, asshown and described, and for the purpose specified.

2. In abandcutter and feeder for thrashing-machines, the combination ofthecylinder B, the vibratory feed-board D, the dividers ff, and theelevated carrier E, the feed-board standing upright between the cylinderand carrier, and the dividers projecting through the feed-board, asshown and described, and for the purpose specified.

3. In a band-cutter and feeder for thrashing-machines, the combination,with the endless carrier E, of the shaft 1 and teeth a n, attached toand moving with the carrier, and provided with suitable mechanism tocause said teeth to automatically close to grasp the wire band, and toagain open to release and discharge it, as shown and described, and forthe purpose specified.

4. The combination of the shaft 1, teeth a n, spring 7', arms 25 t, andstops u u, as shown and described, and for the purpose specified.

5. In combination with the teeth n a, the plates 19 p, projectingoutward beneath the teeth and serving for the teeth to strike upon toinclose and hold the wire bands, as herein shown and described.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
